Enterprise model verification and validation: an approach

This article presents a verification and validation approach which is used here in order to complete the classical tool box the industrial user may utilize in enterprise modeling and integration domain. This approach, which has been defined independently from any application domain is based on several formal concepts and tools presented in this paper. These concepts are property concepts, property reference matrix, properties graphs, enterprise modeling domain ontology, conceptual graphs and formal reasoning mechanisms.

A formal verification framework and associated tools for enterprise modeling: application to UEML

The aim of this paper is to propose and apply a verification and validation approach to Enterprise Modeling that enables the user to improve the relevance and correctness, the suitability and coherence of a model by using properties specification and formal proof of properties.

Computer-aided decision for human task allocation with mono- and multi-performance evaluation

An efficient Binary Search-based approach used to determine the sets of human resources allowing one to reach, for an enterprise process, a given performance level is presented. It is based on an enterprise process performance methodology integrating human skill influence. In a first step, this approach is compared with algorithms such as Hybrid Taboo-Descent, Simulated Annealing and Knapsack algorithms for different performance points of view (temporal, financial, quality oriented) on limited and large complexity examples. In a second step, this approach is generalized to integrate simultaneously several viewpoints.

Design and analysis of workflow processes with Petri nets

This paper aims to model workflow processes and to analyze them. From an enterprise model, we automatically translate the workflow processes into an equivalent Petri net which allows to check properties of good behavior. Thus, it is possible to verify the good modeling and to detect some process problems in the enterprise.

How to manage coverability graphs construction: an overview

To analyze the behavior of Petri nets, the reachability graph permits us to verify qualitative properties. However, even for small nets, the reachability graph can become infinite if the studied Petri net is unbounded. So, to deal with the state space explosion problem, the coverability graph must be used. The paper aims to expose the main ways of construction of coverability graphs and specifies how some qualitative properties can be checked in these different approaches.

User defined multi-criteria added-value for enterprise processes analysis

Managers need to model and analyze the enterprise processes from different points of view in order to measure their efficiency. The paper focuses on an enterprise modeling approach allowing us to describe and analyze the influence of an activity in a process. The modeling method is based on the definition of a set of criteria related to the users efficiency estimators. The analysis is decomposed into three levels allowing us to qualify qualitatively and quantitatively the studied process.
